[Bug 1788927] [NEW] Removing repo key doesn't work

[Alfred E. Neumayer]

Public bug reported:

Removing an apt key from within the software-properties GUI doesn't work, neither before (when the permission is not granted to the process and cached already) nor after entering the user password in the polkit prompt.
Existance and enabled state of the repository related to the key doesn't influence the result either.

software-properties-gtk --debug doesn't print information about the
deletion of the key either.

Steps to reproduce:
1) Add ppa via add-apt-repository to add an apt repo incl. key import
2) Open software-properties-gtk
3) Jump to the "Authentication" tab
4) Select a key and press the "Remove" button

Expected behaviour:
Key is successfully removed

Actual behaviour:
Key is not removed
